Zvakanakira kutonhora kutonhora kwakaumbwa zvakarukwa zvigadzirwa zvekugadzira
Mukuvaka uye kugadzira zvikamu, sarudzo yekugadzira midziyo uye nzira dzinoita basa rakakosha mune yakabudirira kupedzisa chero chirongwa. Chimwe chinhu chakadai chakakurumbira mumakore achangopfuura chinotonhora-chakaumbwa chakaumbwa pombi. Ichi chigadzirwa chinogadzirwa chinopa akati wandei zvakanakira pamusoro pemubhadharo wesamushi wekusungwa kana wakabatanidzwa, kunyanya spiral seam pombi.
Kutonhora akaumbwa akaumbwaPIPE yakagadzirwa kuburikidza nechitonhora-fomu yekugadzira, iyo inosanganisira kukotama uye kuumba koriyamu yesimbi mune chimiro chaunoda. Mhedzisiro iyi pombi iyo iri mbiri yakasimba uye yakasimba, asi yakaremara uye nyore kushandisa. Pamusoro pezvo, maitiro anotonhora ekuumba anovimbisa kuti pombi inochengetedza kutendeka kwayo kwekuvimbika uye kurongeka kwakazara, kuchiita kuti ive yakakodzera kuti ibate mashandisirwo.

Hydrostatic test
Kureba kwepepe kuchaidzwa nemugadziri kune hydrostatic kumanikidza kuchagadzira madziro kushushikana kwekushaiwa makumi matanhatu muzana yeiyo yakasarudzika shuwa simba rekubereka tembiricha. Dzvinyiriro ichatsanangurwa neiyo inotevera equation:
P = 2st / d
Zvinotenderwa kusiyana kwehuremu uye zviyero
Kureba kwega kwega kwembwa kucharemerwa zvakasiyana uye kurema kwayo hakuzopindirane kupfuura gumi muzana pamusoro kana 5.5% pasi pehuremu hwayo uye huremu hwayo uye huremu hwayo pahurefu.
Iyo yekunze dhisiki haizosiyane kupfuura ± 1% kubva pane yakatarwa zita rekunze kunze kwedhimoni.
Kukudza kwemadziro chero nguva hakusi kupfuura gumi nemairi% pasi peiyo yakataurwa madziro.
Kureba
Hurefu hwakasarudzika: 16 kusvika 25ft (4.88 kusvika 7.62m)
Kaviri akareba kureba: Pamusoro pe25ft kusvika ku15ft (7.62 kusvika 10.67m)
Yunifomu Yakareba: Inotenderwa Kusiyana ± 1in
Magumo
Pipe Piles ichagadzirwa nebani magumo, uye burrs kumahombekombe
Kana iyo pombi yekupedzisira yakatsanangurwa kuve yechiodzwa magumo, iyo angle ichave nemakumi matatu kusvika ku35 degree
Imwe yezvakanakisa zvakanakira kutonhora-yakaumbwa yakavezwa kuumbwapombi yeWeldingkugona kwayo kutadzira tembiricha dzakakwirira uye dzvinyiriro. Kusiyana pombi dzechinyakare, iyo inokanganiswa neCorrosion uye dzimwe nzira dzekushambadzira, pombi dzakagadzirwa-dzakaumbwa dzine majini kuti dziregedze mafambiro ezvekutya uye mamwe maindasitiri maitiro. Izvi zvinovaita kuti vazive kushandiswa kwakasiyana-siyana kwekushandisa kubva pakuvaka kuvaka kumapurojekiti emisangano.
Imwe mukana wekutonhora-kwakaumbwa wakaumbwa pombi yemutengo wayo mutengo. Maitiro ekutonhora ekuumba anogona kuburitsa mapipi mune akasiyana-siyana saizi uye maumbirwo, kuderedza kukosha kwekudhura kwekukanda uye michina maitiro. Izvi zvinoita kuti chigadzirwa chiwedzere kukwanisa uye zvakavimbika seyemawinaruki kana kuti yakavezwa pombi. Uye zvakare, iyo yakareruka midziyo yendewe inotonhora-yakaumbwa inoita kuti kutakura uye kuisirwa nyore uye zvakanyanya mutengo-zvinobudirira, kuwedzera kuwedzera kukwikwidza kwayo.
Spiral seam machubhu anonyatso batsirwa kubva pakutonhorera maitiro ekugadzira. Simba rinoshamisa uye kushandurwa kwekutonhama kwekuumbwa kunoumbwa maTubes kunovaita kuti vagadzire kuti vagadzike nekukasira uye kusvetuka-chiratidzo majoini. Izvi zvinovaita sarudzo yakanaka kwazvo yekushandisa senge pasi pevhu masisitimu emvura, mitsara yemvura uye kunyange yekurima inodzivirira system. Pamusoro pezvo, nzvimbo yakatsiga yemapepa anotonhora-yakaumbwa anoderedza njodzi yekukakavara uye kupfeka, kuwedzera hupenyu hwePIPE uye kuderedza kudiwa kwekugadzirisa uye kugadziriswa.
Zvakazara, kutonhora kwakaumbwa wakaumbwa pombi yemhando inopa nhamba yezvakanakira izvo zvinoita kuti ive sarudzo yakanaka yekunyorera zvikumbiro, kunyanya spiral seam pombi. Simba ravo, kusimba uye mutengo-zvinobhadhara zvinoita kuti vave nesarudzo inokwezva yehuremu hwakawanda hwemaindasitiri, kubva pakuvaka kuti ugadzire. Sezvo kudiwa kwemhando yepamusoro-mhando, kuvimbika zvinhu zvinoenderera kukura, kutonhora-kwakaumbwa zvakarongeka pombi kuchava chisarudzo chakawedzera chakakurumbira cheWelding Zvikumbiro.
